The outcome of the events described in these forward-looking statements is subject to risks, uncertainties and other factors referenced in section Item 1.A “Risk Factors” in this Quarterly Report on Form 10-Q.

New risks and uncertainties emerge from time to time, and we cannot predict all risks and uncertainties that could impact the forward-looking statements contained in this Quarterly Report on Form 10-Q. The results, events and circumstances reflected in the forward-looking statements may not be achieved or occur, and actual results, events or circumstances could differ materially from those described in the forward-looking statements.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based on information available to us as of the date of this Quarterly Report on Form 10-Q. While we believe that information provides a reasonable basis for these statements, that information may be limited or incomplete. Our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all relevant information. These statements are inherently uncertain, and investors are cautioned not to unduly rely on these statements.

The forward-looking statements in this Quarterly Report on Form 10-Q relate only to events as of the date the statements are made. We undertake no obligation to update any forward-looking statements made in this Quarterly Report on Form 10-Q to reflect events or circumstances after the date of this Quarterly Report on Form 10-Q or to reflect new information or the occurrence of unanticipated events, except as required by law. We may not achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. Our forward-looking statements do not reflect the potential impact of future acquisitions, mergers, dispositions, joint ventures or investments.

Notes to Unaudited Condensed Consolidated Financial Statements

(1) Organization

Description of business

SunPower Inc. (“SunPower” or the “Company”) is the rebranded name of Complete Solaria, Inc. (“Complete Solaria”). The rebranding was effective April 22, 2025 and the Company’s legal name change became effective on October 16, 2025. References to the Company and SunPower include the same entity under its previous name of Complete Solaria. The Company is headquartered in Orem, Utah.

The Company was originally incorporated in Delaware under the name Complete Solaria, Inc. and is a residential solar installer that offers storage and home energy solutions to customers in North America. The Company was formed through Complete Solar Holding Corporation’s acquisition of The Solaria Corporation (“Solaria”).

Complete Solar, Inc. (“Complete Solar”) was incorporated in Delaware on February 22, 2010. Through February 2022, the Company operated as Complete Solar, Inc., a single legal entity. In February 2022, Complete Solar implemented a holding company reorganization (the “Reorganization”) in which the Company created and incorporated Complete Solar Holding Corporation (“Complete Solar Holdings”). As a result of the Reorganization, Complete Solar Holdings became the successor entity to Complete Solar, Inc. Complete Solaria, Inc. (“Complete Solaria”) was formed in November 2022 through the merger of Complete Solar Holding Corporation, a Delaware corporation (“Complete Solar”), and The Solaria Corporation, a Delaware corporation (such entity, “Solaria,” and such transaction, the “Business Combination”).

The Company operates on a 52-to-53-week fiscal year that ends on the Sunday closest to December 31. The Company’s first fiscal quarters for 2026 and 2025 in this report on Form 10-Q ended on March 29, 2026 (“Q1 2026”) and March 30, 2025 (“Q1 2025”), respectively.

Acquisitions

In the fiscal year ended December 28, 2025, the Company completed the acquisitions of Sunder Energy, LLC (“Sunder”) and Ambia Energy LLC (“Ambia”). On February 2, 2026, the Company completed the acquisition of Cobalt Power Systems, Inc. (“Cobalt”). Each of these acquisitions was accounted for as a business combination in accordance with Accounting Standards Codification (“ASC”) 805, Business Combination. Refer to Note 3 – Business Combinations for details of these transactions.

Liquidity and going concern

The Company’s operating loss was $19.2 million in the thirteen weeks ended March 29, 2026. As of March 29, 2026, the Company had an accumulated deficit of $451.5 million, current debt of $38.0 million, and cash and cash equivalents, excluding restricted cash, of $9.5 million. The Company anticipates that operating losses and negative operating cash flows will continue in the near term.

Management is actively pursuing plans to mitigate these conditions, including obtaining additional capital resources through equity or debt financing and leveraging support from significant stockholders when necessary. The Company has financed its operations primarily through sales of equity securities, private placements, debt, issuance of convertible notes and other debt instruments, other financing instruments, cash from operations, and proceeds from the Mergers.

The Company did not file its Quarterly Report on Form 10-Q for the quarter ended September 28, 2025 or the amendment required to the Current Report originally filed on September 26, 2025, relating to the Sunder acquisition, within the timeframe required by the SEC. As a result, the Company is not currently eligible to use a registration statement on Form S-3 that would allow it to continuously incorporate by reference its SEC reports into a registration statement, to use “shelf” registration statements to conduct offerings, or to use the at-the-market offering facility until approximately one year from the date that the Company has regained and maintained status as a current filer. Aside from a “shelf” registration, the Company has alternative financing options and may seek additional liquidity through the use of a Form S-1 registration statement and or private placements.

If the Company is not able to secure adequate additional funding when needed, the Company will need to reevaluate its operating plan and may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible, or suspend or curtail planned programs or cease operations entirely. These actions could materially impact the Company’s business, results of operations and future prospects. While the Company has been able to raise multiple rounds of financing, there can be no assurance that in the event the Company requires additional financing, such financing will be available on terms that are favorable, or at all. Failure to generate sufficient cash flows from operations, raise additional capital or reduce certain discretionary spending would have a material adverse effect on the Company’s ability to achieve its intended business objectives.

Therefore, there is substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the unaudited condensed consolidated financial statements are issued. The accompanying unaudited condensed consolidated financial statements have been prepared assuming the Company will continue to operate as a going concern, which contemplates the realization of assets and settlement of liabilities in the normal course of business. They do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from uncertainty related to its ability to continue as a going concern.

(2) Basis of Presentation and Summary of Significant Accounting Policies

Basis of presentation

The interim unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation.

The accompanying interim unaudited condensed consolidated financial statements are unaudited and have been prepared by the Company in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, these interim unaudited condensed consolidated financial statements do not include all the information and disclosures required by U.S. GAAP for complete financial statements.

In the opinion of management, these interim unaudited condensed consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, necessary to present fairly the Company’s financial position as of March 29, 2026, and the results of operations for the thirteen weeks ended March 29, 2026 and March 30, 2025. These interim unaudited condensed consolidated financial statements and related notes should be read in conjunction with the audited consolidated financial statements and related notes for the fiscal year ended December 28, 2025, included in the Company’s Annual Report on Form 10-K filed with the SEC on April 14, 2026. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year or any other future period.

Use of estimates

The preparation of interim unaudited condensed consolidated financial statements requires management to make estimates and assumptions that affect reported amounts.

Revenue recognition

The Company recognizes revenue in accordance with ASC 606 – Revenue from Contracts with Customers (“ASC 606”) when control of the promised products and services is transferred to the customer and its performance obligations are satisfied. The Company’s performance obligation in its Residential Solar Installation and New Homes Business segments is to design and install a fully functioning solar energy system. The design, delivery of system components, installation, and services facilitating interconnection to the power grid are accounted for as a single performance obligation.

Revenue is recognized in the amount of consideration the Company expects to be entitled to receive, net of customer incentives such as discounts or rebates, and variable consideration is estimated at each reporting date to the extent it is probable that a significant reversal will not occur. Amounts invoiced and collected in advance of performance are recorded as deferred revenue. The Company’s contracts do not contain significant financing components.

For Residential Solar Installation and New Homes Business cash and financing arrangements, revenue is generally recognized over time beginning when the system is fully installed, as this is when the customer obtains control of the asset. Revenue is recognized using an input method based on direct installation costs. For New Homes Business lease arrangements, revenue is recognized at a point in time upon customer acceptance of the completed system.

In the Dealer segment, the Company earns revenue from contracts for solar installations performed by third-party installers. The Company acts as an agent in these arrangements and recognizes revenue on a net basis at the point in time when substantial completion is achieved. The Company does not provide warranty services related to Dealer contracts. During the thirteen week period ended March 29, 2026, the Company amended customer contracts and under the amended contractual terms, the point at which control transfers to the customer changed from permission to operate (“PTO”) to substantial completion of the installation. As a result, the Company recognized incremental revenue of $12.4 million in the thirteen week period ended March 29, 2026, related to the contract modifications.

Incremental costs of obtaining customer contracts

As of March 29, 2026 and December 28, 2025, deferred commissions were $8.1 million and $5.6 million, respectively.

(3) Business Combinations

Cobalt Power Systems, Inc.

On January 30, 2026, the Company entered into a Share Purchase Agreement (the “Share Purchase Agreement”) with Cobalt and Cobalt’s stockholders (the “Cobalt Stockholders”). The Company, Cobalt and the Cobalt Stockholders completed the closing under the Share Purchase Agreement (the “Cobalt Closing”) on February 2, 2026. At the Cobalt Closing, the Company acquired all of the outstanding stock of Cobalt from the Cobalt Stockholders for: (a) 1.8 million shares (the “Closing Consideration Shares”) of the Company’s common stock and (b) an agreement to issue an additional $3.33 million of shares of the Company’s common stock on each of the 12-month and 18-month anniversaries of the Cobalt Closing (“Post-Closing Consideration Shares). Additionally, the Company agreed to issue up to $2.0 million of restricted stock units to those Cobalt employees who continue their employment with the Company following the Cobalt Closing, and 850,000 restricted stock units will be issued as inducement grants to certain Cobalt key employees. Based on the analysis of the payments made or to be made in connection with the acquisition of Cobalt under ASC 805, the Company concluded that the $2.0 million of restricted stock units is considered compensation and, therefore, this amount has been excluded from the business combination consideration. Cobalt designs and installs solar systems for residential and commercial clients.

Total consideration for Cobalt was $9.66 million, which consists of $3.33 million paid at the Cobalt Closing and Post-Closing Consideration Shares valued at $6.33 million. The $3.33 million fair value of the shares of common stock issued at the Cobalt Closing was derived based on the Company’s closing stock price in a 5-day volume-weighted average price (“VWAP”) immediately preceding the Cobalt Closing to determine the number of shares issued. The Post-Closing Consideration Shares are treated as a liability for financial reporting purposes and are reported within Deferred consideration, current and deferred consideration, noncurrent within the Company’s unaudited condensed consolidated balance sheet, and were valued using a Monte Carlo simulation model to capture the variability in the number and value of shares issuable at the 12- and 18-month post-closing dates. Under the terms of the agreement, the deferred obligation represents a fixed dollar amount that will be settled in a variable number of shares determined based on the 5-day VWAP immediately prior to each issuance date, resulting in an inverse relationship between share price and shares issued. The model incorporates key assumptions, including a starting VWAP of $1.69, a risk-free rate of 3.53%, expected volatility of 85.5% derived from peer company analysis and historical data, and a 1.5-year simulation horizon. For each simulated stock price path, the model calculates the resulting share issuances and corresponding payment values, discounts those amounts to present value, and averages the outcomes across simulations to estimate fair value, resulting in a concluded value of approximately $6.33 million as of the valuation date. The total consideration is summarized as follows (in thousands):

Consideration
Fair value of shares of the Company’s common stock issued at Cobalt Closing (classified within Additional paid-in capital)	$	3,333
Deferred Cobalt Consideration Shares (Classified within Deferred consideration, current and noncurrent)		6,331
Fair value of total consideration	$	9,664

The provisional fair values of assets acquired and liabilities assumed were based upon the facts and circumstances existing at the Cobalt Closing. The purchase price accounting remains open for the valuation of intangibles, certain liabilities and allocation of goodwill. The Company elected the practical expedient within ASC 805-20-30-27 through 805-20-30-30 to recognize and measure contract liabilities in accordance with ASC 606 as if it had originated the acquired contract. Thus, the amount of any contract liabilities immediately prior to the acquisition will be the comparable amounts recognized in the determination of assets acquired and liabilities assumed by the Company.

The provisional fair values of identifiable assets acquired and liabilities assumed are identified below (in thousands):

	Provisional fair values as of Cobalt Closing
Net assets acquired:
Cash and cash equivalents	$	553
Trade accounts receivable, net		3,642
Inventories		1,739
Prepaid expenses and other current assets		30
Property and equipment, net		485
Intangible assets, net		3,871
Operating lease right-of-use assets		1,277
Accounts payable		(3,864	)
Accrued expenses and other current liabilities		(1,002	)
Short-term debt with third parties		(2,706	)
Other long-term liabilities		(1,099	)
Contract liabilities		(5,238	)
Deferred tax liability		(1,001	)
Fair value of the excess of liabilities assumed over assets acquired		(3,313	)
Fair value of common stock issued		3,333
Fair value of Deferred Cobalt Consideration Shares		6,331
Consideration transferred		9,664
Goodwill recognized	$	12,977

As of the date of acquisition, the intangible assets acquired and estimated useful lives were as follows:

	Estimated useful life	Provisional fair values as of the Cobalt Closing
Customer relationships (Backlog)	18 months	$	1,100
Trade name – Cobalt	10 years		2,000
Building lease intangible asset – favorable lease	6 years		771
Total		$	3,871

The fair value of the backlog was estimated using the excess earnings method, an income-based approach, under which value is determined based on the present value of the cash flows attributable specifically to the backlog after deducting appropriate returns for contributory assets. Projected revenues were based on the contractual backlog existing as of the valuation date, and operating expenses were estimated as a percentage of revenue, with an adjustment to exclude sales and marketing expenses. Based on management’s estimates, substantially all sales and marketing efforts relate to acquiring new customers and are not required to fulfill the existing backlog. Contributory asset charges were applied for the use of working capital, fixed assets, assembled workforce, and trademarks.

The trade name’s fair value was estimated using the relief-from-royalty method, which measures the present value of avoided royalty payments. The valuation considered qualitative factors such as Cobalt’s long operating history since 2003, strong reputation for affordable and reliable solar solutions, and established market presence with over 2,400 installations. It assumed the trade name supports all revenues and applied a 1.0% royalty rate based on profit-split analysis and market data. The trade name was assigned a 10-year useful life, reflecting expected continued use and brand support

The fair value of the building lease was estimated using an income approach, specifically a discounted cash flow model, reflecting the present value of the difference between contractual rent and estimated market rent over the remaining lease term. Key assumptions include a market rent derived from comparable properties, a 2.0% annual rental growth rate, and an 8.50% discount rate consistent with market participant return expectations and leasehold-specific risks.

Goodwill represents the excess of the preliminary estimated consideration transferred over the fair value of the net tangible and intangible assets acquired that is associated with the excess cash flows that the acquisition is expected to generate in the future. The goodwill is not deductible for tax purposes.

Cobalt contributed $5.0 million and $0.3 million in revenue and income before income taxes from operations, respectively, for the period from the acquisition date to March 29, 2026.

Sunder Energy LLC

On September 21, 2025, a subsidiary of the Company entered into a Membership Interest Purchase Agreement (“Sunder MIPA”) with Sunder Energy LLC (“Sunder”) and the seller, Chicken Parm Pizza LLC (“CPP”), the sole member of Sunder. On September 24, 2025 (“Sunder Closing”), the Company completed the acquisition of the membership interests of Sunder for an aggregate consideration of $57.8 million (“Sunder Acquisition”). Per the terms of the Sunder MIPA, the Company acquired all of the outstanding membership interest of Sunder for (1) $20.7 million in cash, subject to certain working capital and other adjustments; (2) a promissory note to the Member in the principal amount of $20.0 million (“Seller Note”); and (3) 10.0 million shares of the Company’s common stock (valued at the closing share price on September 24, 2025, of $1.71 per share), consisting of (i) 3.3 million shares of the Company’s common stock issued at the Sunder Closing and (ii) subject to approval of such issuances by the Company’s stockholders, (x) 3.3 million shares of the Company’s common stock to be issued on the 12-month anniversary of the Sunder Closing and (y) 3.3 million shares of the Company’s common stock to be issued on the 18-month anniversary of the Sunder Closing (“Deferred Sunder Consideration Shares”). In lieu of issuing the Deferred Sunder Consideration Shares, the Company, in its sole discretion, may elect to pay the Member a cash payment equal to the number of Deferred Sunder Consideration Shares otherwise issuable by the Company multiplied by the volume-weighted average price of the Company’s common stock as quoted on Nasdaq for the 30-trading day period ending two business days prior to the date on which the applicable Deferred Sunder Consideration Shares are otherwise issuable (“Cash in Lieu Amount”). If the Company elects to pay the Cash in Lieu Amount, 50% of the Cash in Lieu Amount will be paid on the three-month anniversary of the date on which the applicable Deferred Sunder Consideration Shares are otherwise issuable, with the remaining 50% of the Cash in Lieu Amount payable on the six-month anniversary of the date on which the applicable Deferred Sunder Consideration Shares are otherwise issuable. The shares of the Company’s common stock issued and expected to be issued were valued at aggregate of $17.1 million at the Sunder Closing. The common stock issued at the Sunder Closing was valued at $5.7 million and accounted for within Additional paid-in-capital on the Company’s consolidated balance sheet.

On April 23, 2026, the Company and CPP entered into an amended and restated Seller Note that, following certain payoffs under the prior Seller Note, has an amended principal amount of $7.0 million (the “A&R Seller Note”). Refer to Note 18 – Subsequent Events for details.

On March 25, 2026, the Company’s stockholders approved the issuance of the Deferred Sunder Consideration Shares, and the Company’s option to pay the Cash in Lieu Amount expired. Accordingly, the value of the Deferred Sunder Consideration Shares became fixed on that date. The fair value of the 6.7 million Deferred Sunder Consideration Shares was $8.5 million as of March 25, 2026. Under ASC 815-40, Derivatives and Hedging, as all of the substantive contingencies have been resolved and only remaining condition is the passage of time, the obligation met the criteria for equity classification. As such, the Company reclassified the Deferred Sunder Consideration Shares obligation from liability to equity as of March 29, 2026. Pursuant to an Amendment and Agreement dated as of March 5, 2026 between CPP and the Company, the Company agreed to issue all of the Deferred Sunder Consideration Shares following receipt of approval by the Company’s stockholders, and the Deferred Sunder Consideration Shares were subsequently issued on April 8, 2026. Refer to Note 18 – Subsequent Events for details.

The Company concluded that since the sellers joined the Company and represent members of management, they have a level of influence that is not insignificant; therefore, they are related parties to the Company.

Sunder is a solar sales company. The Company acquired Sunder as a strategic acquisition to expand its overall market share and its penetration into more U.S. states. The financial results of Sunder have been included in the Company’s consolidated financial statements since its date of acquisition.

The consideration initially paid and remaining payable as of the date of the Sunder Closing is summarized below (in thousands):

	Consideration
Paid at Sunder Closing
Cash	$	20,689
Seller note		20,000
Fair value of 3.3 million shares of the Company’s common stock		5,700
Payable subsequent to Sunder Closing
Deferred Sunder Consideration Shares (fair value of 6.7 million shares of the Company’s common stock at Sunder Closing)		11,400
Fair value of total consideration at Sunder Closing	$	57,789

The Company financed a portion of the transaction through the issuance of $22.0 million of 7.0% senior unsecured convertible notes (the “September 2025 Notes”) and Seller Note in the original principal amount of $20.0 million, which has been amended by the A&R Seller Note in the principal amount of $7.0 million subsequent to March 29, 2026. Refer to Note 9 – Borrowings and Derivative Liabilities and Note 18 – Subsequent Events for details regarding these obligations.

The provisional fair values of assets acquired and liabilities assumed were based upon a preliminary valuation, and the Company’s estimates and assumptions have been revised during the measurement period to refine the fair values of the assets acquired and liabilities assumed based upon the facts and circumstances existing at the date of acquisition which resulted in the measurement period adjustments noted below. The purchase price accounting remains open for the components of working capital, identification and valuation of intangibles and allocation of goodwill. The Company has elected the practical expedient within ASC 805-20-30-27 through 805-20-30-30 to recognize and measure contract liabilities in accordance with ASC 606 as if it had originated the acquired contract. Thus, the amount of any contract liabilities immediately prior to the acquisition will be the comparable amounts recognized in the determination of assets acquired and liabilities assumed by the Company.

The following table summarizes the provisional fair value of identifiable assets acquired and liabilities assumed. No measurement period adjustments were recorded in the thirteen week period ended March 29, 2026.

(in thousands)	Provisional fair values
Net assets acquired:
Accounts receivable	$	797
Prepaid expenses and other current assets		3,039
Property and equipment		241
Operating lease right-of-use assets		313
Other noncurrent assets		135
Intangibles		37,500
Contract liabilities		(11,673	)
Accounts payable		(203	)
Accrued expenses and other current liabilities		(3,850	)
Operating lease liabilities		(332	)
Fair value of net assets acquired		25,967
Consideration transferred		57,789
Goodwill recognized	$	31,822

Intangible assets acquired and estimated useful lives were as follows (in thousands):

	Estimated useful life	Provisional fair values
Customer relationships	10 years	$	30,600
Trademark - Sunder	10 years		6,100
Developed technology - Sunder	2 years		800
Total		$	37,500

The fair value of customer relationships was estimated using the excess earnings method. The assumptions used included revenue, included all business enterprise valuation sales, reduced by a 5% attrition rate based on historical customer turnover, with operating expenses estimated as a percentage of sales and no sales-and-marketing adjustment since such efforts do not directly support existing customers. Contributory asset charges were applied for the use of working capital, fixed assets, workforce, trademarks, and internal-use software, and cash flows were projected over the period in which customer relationships were expected to produce meaningful benefit, with the economic life extending until those cash flows became minimal.

The fair value of the trademark was estimated using the relief-from-royalty method. This approach measures the value of the asset based on the hypothetical royalties the Company would avoid paying if it had to license the trademark from a third party. The assumptions used to value the trademark included projected sales based upon the business enterprise valuation considered attributable to the trademark, a royalty rate of 1.0% supported by a profit-split analysis and benchmarking against comparable licensing arrangements in the solar and broader energy industries and a useful economic life of 10 years consistent with management’s expectations for continued use and the anticipated longevity of the brand’s market relevance.

The fair value of Sunder’s developed technology was estimated using the cost approach, which measures value based on the cost to reproduce or replace the existing software in its current state. The analysis considered the historical direct development costs, including Sunder’s ongoing investment in labor, design, coding, and testing efforts required to build the technology. In addition to direct costs, the valuation incorporated opportunity costs, which reflect the portion of the software expected to be added, modified, or removed over time based on management’s estimates of ongoing development needs. Together, these inputs approximate the current replacement cost of the technology, adjusted for necessary updates and functional improvements.

Ambia Energy LLC

On November 21, 2025, the Company entered into a Membership Interest Purchase Agreement (the “Ambia MIPA”) with Ambia and Ambia Holdings, Inc., a Delaware corporation and the sole member of Ambia (“Ambia Holdings”) to acquire Ambia (the “Ambia Acquisition”). Ambia was the sole operating entity within Ambia Holdings. Ambia is a residential solar energy system installer and operates in various markets throughout the United States.

The Company, Ambia and Ambia Holdings completed the closing under the Ambia MIPA on November 21, 2025 (the “Ambia Closing”). At the Ambia Closing, the Company acquired all of the outstanding membership interests of Ambia from Ambia Holdings for: (a) 10,243,924 shares of common stock of the Company (the “Ambia Closing Consideration Shares”), issued at the Ambia Closing to Ambia Holdings; and (b) an agreement to issue an additional 9.375 million of shares of the Company’s common stock on each of the six-month anniversary of the Ambia Closing and the 12-month anniversary of the Ambia Closing (collectively such additional shares of common stock, the “Deferred Ambia Consideration Shares”). The issuance of the Deferred Ambia Consideration Shares is subject to approval by the Company’s stockholders following the Ambia Closing. On March 25, 2026, the Company’s stockholders approved the issuance of the Deferred Ambia Consideration Shares.

The actual number of Deferred Ambia Consideration Shares issuable by the Company on the six- and 12-month anniversaries of the Ambia Closing will be determined based on the 20-day trailing volume-weighted average price of the Company’s common stock after market close on the business day immediately prior to the issuance date of the applicable shares (the “VWAP Value”); provided that the VWAP Value for the calculation of the actual number of Deferred Ambia Consideration Shares issuable by the Company will not be more than $2.8102 per share or less than $1.4988 per share. Additionally, the number of Deferred Ambia Consideration Shares issuable by the Company is subject to adjustment pursuant to customary working capital and balance sheet adjustment terms and subject to offset for certain indemnifiable damages in accordance with the Ambia MIPA.

The initial fair value of the deferred consideration shares at the Ambia Closing was $16.9 million. The Company’s closing share price for its common stock of $1.61 on November 21, 2025 was used to fair value the shares issued at the Ambia Closing. The total consideration is summarized as follows (in thousands):

Consideration
Fair value of 10,243,924 shares of the Company’s common stock issued at Ambia Closing	$	16,493
Deferred Ambia Consideration Shares		16,879
Fair value of total consideration	$	33,372

The provisional fair values of assets acquired and liabilities assumed were based upon the facts and circumstances existing at the date of acquisition. The purchase price accounting remains open for the valuation of the customer relationship and allocation of goodwill. The Company elected the practical expedient within ASC 805-20-30-27 through 805-20-30-30 to recognize and measure contract liabilities in accordance with ASC 606 as if it had originated the acquired contract. Thus, the amount of any contract liabilities immediately prior to the acquisition will be the comparable amounts recognized in the determination of assets acquired and liabilities assumed by the Company.

There have been no measurement period adjustments since the Ambia Closing. The provisional fair values of identifiable assets acquired and liabilities assumed are identified below (in thousands):

Customer relationships (Backlog)	1 year ⁽¹⁾	$	3,400
Trademarks - Ambia	1 year		900
Total		$	4,300

(1)

Useful life is based upon customer consumption, expected to occur within one year.

Trademarks were derived using the relief from royalty method based upon the following key assumptions; (i) all sales based upon the business enterprise value; (ii) a royalty rate of 1% based upon profit split analysis and comparable licensing royalty agreements; and (iii) an economic life of the Ambia name through the end of 2026, wherein the Ambia name will only be used in certain small markets and that all sales, marketing and branding will be done under the SunPower brand name in relatively short order.

Customer relationships (backlog) was derived using the excess earnings method based upon the following key assumptions: (i) backlog meets the appropriate contractual criteria; (ii) sales were based upon the backlog of sales; (iii) expenses were based upon a percentage of sales with an adjustment for sales and marketing expenses, upon which management estimates that 100% of Ambia’s sales and marketing expenses are directed at acquiring new customers and are not required to support the backlog; (iv) charges were taken for the use of working capital, fixed assets, workforce and trademarks; and (v) the economic life of the backlog is to the end of fiscal 2026 based upon management’s estimate of average deal length.

Derivative liabilities

The Company recognized derivative liabilities arising from the conversion features of its senior unsecured convertible notes issued (refer to Note 9 – Borrowings and Derivative Liabilities). Derivative liabilities are measured at fair value in accordance with ASC 820, Fair Value Measurement. The fair value of each respective derivative liability is measured using a Monte Carlo simulation that incorporates a binomial lattice model. Significant inputs to the binomial lattice model include the terms of the senior unsecured convertible notes (including the interest rate, conversion rate and conversion price), the underlying price of the Company’s common stock, risk-free rate and volatility. Certain of these inputs are unobservable. Thus, these derivative liabilities are classified within Level 3 of the fair value hierarchy. The binomial lattice model produces an estimated fair value based on changes in the price of the underlying shares of the Company’s common stock over successive periods of time. As a result of these interrelationships and inherent unobservable assumptions, the fair value of a derivative liability is subject to significant measurement uncertainty, and alternative reasonable assumptions could have produced materially different results as of March 29, 2026 and December 28, 2025.

The assumptions used to value the derivative liabilities as of March 29, 2026 were as follows:

The conversion option is derived based upon the above assumptions plus a make-whole provision which is based upon changes in the Company’s stock price and the conversion date.

$1.9 Million Note and March 2026 Bridge Note

The Company elected the fair value option under ASC 825 for the $1.9 Million Note (as defined in Note 9 – Borrowings and Derivative Liabilities) issued on January 27, 2026 in connection with the Standby Equity Purchase Agreement (as defined in Note 9 – Borrowings and Derivative Liabilities) and the March 2026 Bridge Note (as defined in Note 9 – Borrowings and Derivative Liabilities) issued on March 6, 2026. The $1.9 Million Note and March 2026 Bridge Note were measured at fair value on a recurring basis and classified as a Level 3 liability due to the use of significant unobservable inputs.

The Company estimated the fair value of each obligation using a Monte Carlo simulation model, which captures the economic characteristics of the instrument, including its variable conversion price feature that is dependent on future market prices of the Company’s common stock. The Company utilized a “Bond plus Option” approach, where the value of upside plus amortization was determined in a simulation and the value related to principal repayment was calculated as a single payment of principal at maturity. The Company simulated its stock price from the valuation date to maturity date, at a daily step.

With respect to the $1.9 Million Note, on each of the simulated paths, the Company (i) tested for an amortization trigger as applicable; and (ii) assumed that the maturity date will not be extended. Once the payoffs for all simulation paths were determined according to above, they were discounted back to the valuation date at the risk-free rate in case the $1.9 Million Note would be converted and at credit risk-adjusted rate otherwise.

With respect to the March 2026 Bridge Note, on each of the simulated paths, the Company determined the maximum payoff on each installment date based on conversion price. Once the payoffs for all simulation paths were determined according to above, they were discounted back to the valuation date at the risk-free rate in case the March 2026 Bridge Note would be converted and at credit risk-adjusted rate otherwise.

The fair value of these obligations was each calculated as the average present value across all simulation paths plus present value of debt component. The model was calibrated to transaction proceeds by varying credit risk-adjusted rate in the model. The change in yields between the valuation dates was applied to the credit risk-adjusted rate to account for market changes. Thus, these obligations are classified within Level 3 of the fair value hierarchy as the fair values are based upon unobservable inputs.

The key inputs for the simulation include stock price, simulation period and volatility of the Company’s common stock and were as follows as of March 29, 2026:

	$1.9 Million Note			March 2026 Bridge Note
VWAP stock price	$	1.24		$	1.24
Simulation period		0.83 years			0.94 years
Risk-free rate		3.76	%		3.77	%
Volatility		81.4	%		83.3	%
Credit risk-adjusted rate		41.4	%		73.4	%

The fair value measurement reflects a probability-weighted assessment of settlement outcomes, including conversion into equity versus cash repayment scenarios, and captures the optionality inherent in the instrument. Changes in these assumptions, particularly stock price volatility, credit spread, and the likelihood of conversion, can result in significant fluctuations in the estimated fair value. Changes in fair value are recognized in operating results within “Other non-operating income, net,” in the Company’s unaudited condensed consolidated statements of operations and comprehensive income, and no separate interest expense is recorded, as the fair value measurement incorporates the economic cost of the financing.

Public warrants

The public warrants are measured at fair value on a recurring basis. The public warrants were valued based on the closing price of the publicly traded instrument and therefore are considered a Level 1 instrument in the fair value hierarchy.

Private placement and working capital warrants

The Company valued the private placement and working capital warrants, based on a binomial lattice model, which included the following inputs:

	As of
	March 29,			December 28,
	2026			2025
Expected term		2.31 years			2.56 years
Stock price	$	1.25		$	1.62
Exercise price	$	11.50		$	11.50
Expected volatility		268.3	%		179.0	%
Risk-free rate		3.90	%		3.50	%
Expected dividend yield		0.00	%		0.00	%

The expected term is the time period to the expiration date of the warrants. The risk-free rate is interpolated from the U.S. Constant Maturity Treasury curve for a term matching the corresponding remaining life. Volatility was calibrated based on the public warrants closing price as of the valuation date. As the private and working capital warrants have terms nearly identical to the publicly traded warrants, the volatility was calibrated until the model price equaled the public warrants closing price. These inherent unobservable assumptions are subject to significant measurement uncertainty, and alternative reasonable assumptions could have produced materially different results as of March 29, 2026 and December 28, 2025. Thus, the private placement and working capital warrant liabilities are classified within Level 3 of the fair value hierarchy.

Forward purchase agreement (“FPA”) liabilities

FPAs are measured at fair value on a recurring basis using a Monte Carlo simulation analysis based upon the following inputs:

	As of
	March 29,			December 28,
	2026			2025
VWAP stock price	$	1.24		$	1.66
Simulation period		0.30 years			0.55 years
Risk-free rate		3.73	%		3.57	%
Volatility		58.0	%		77.3	%

The volume-weighted average price (“VWAP”) reflects management’s judgment regarding expected future trading activity and price behavior as an active forward market does not exist for the Company’s common stock. Reasonably possible alternative VWAP outcomes at the reporting date could have resulted in a materially different fair value. The risk-free rate is derived from the applicable tenor of the U.S. Treasury yield curve. Changes in the risk-free rate would alter the present value of the simulated settlement amounts and could significantly impact the fair value estimate. The expected volatility is determined based on the historical equity volatility of comparable companies over a period that matches the simulation period. Because expected volatility drives the dispersion of simulated price paths, reasonably higher or lower volatility assumptions could materially increase or decrease the estimated fair value. These inputs are interrelated, and changes in one may affect the others. As a result of these interrelationships and inherent unobservable assumptions, the fair value of FPAs is subject to significant measurement uncertainty, and alternative reasonable assumptions could have produced materially different results as of March 29, 2026 and December 28, 2025. Thus, FPAs are classified within Level 3 of the fair value hierarchy.

SAFE agreement with related party

The Company measured the fair value of its SAFE using a valuation technique that incorporates significant unobservable inputs and is therefore classified within Level 3 of the fair value hierarchy. The fair value of the SAFE is subject to estimation uncertainty because it depends on management’s judgments about future events that are not directly observable in active markets. Management assigned a 50% probability that the SAFE will convert into shares of the Company’s stock in connection with a qualifying financing or other specified event. If the SAFE does not convert, management expects cash repayment in fiscal 2026 or fiscal 2027, with a 50% probability assigned to each repayment year.

The SAFE valuation also considers assumptions such as discount rates implied by the Company’s convertible notes as of the valuation date, the timing and likelihood of financing or liquidity events, and, for the conversion path, the expected equity valuation and any applicable conversion economics (e.g., discounts or valuation caps). Settlement of the SAFE is contingent on future financing or liquidity events and the Company’s funding plans. Accordingly, the measurement requires judgment about the likelihood and timing of conversion versus repayment and, where relevant, assumptions about the Company’s equity value at conversion. Because these factors are not directly observable, reasonably possible alternative assumptions at the reporting date could produce a materially different fair value. Increasing the probability of conversion would generally increase the fair value if the conversion terms imply a beneficial outcome to the holder relative to repayment; decreasing that probability would place more weight on the repayment scenarios and could increase or decrease the fair value depending on the applicable discount rate and timing of cash flows. Within the non-conversion path, shifting probability weight toward repayment in fiscal year 2026 would generally increase fair value (lower discounting), while shifting weight toward fiscal 2027 would generally decrease fair value (greater discounting), holding other inputs constant. A higher discount rate would decrease the present value of expected cash flows (and thus fair value), while a lower rate would increase fair value. Higher expected equity values or more favorable conversion economics would increase the fair value under the conversion path; lower expected equity values or less favorable terms would decrease it. These inputs are interrelated and unobservable. Because the valuation depends on significant unobservable inputs—including a 50% probability of conversion to equity and an even allocation between fiscal years 2026 and 2027 of repayment if conversion does not occur—there is significant measurement uncertainty, and alternative reasonable assumptions at the reporting date could have resulted in a materially different fair value of the SAFE liability as of March 29, 2026 and December 28, 2025. Thus, the SAFE liability is classified within Level 3 of the fair value hierarchy.

Deferred Ambia Consideration Shares

The Deferred Ambia consideration is classified within Level 3 of the fair value hierarchy.

The Company estimated the fair value of the deferred consideration shares using a Turnbull–Wakeman closed-form approximation for arithmetic average-rate options, with Black-Scholes values used as an upper bound. The valuation as of March 29, 2026, was based on a stock price of $1.25 and key assumptions including expected volatility of approximately 52% to 72%, risk-free rates of approximately 3.74% to 3.76%, zero dividend yield, and defined averaging periods over the contractual terms. The resulting fair values reflect per-unit option values of approximately $0.26 to $0.38 corresponding to total estimated value of $13.9 million. The fair value of the deferred consideration shares as of December 28, 2025 of $16.9 million was estimated using the Company’s closing share price for its common stock of $1.61 at the Ambia Closing.

The actual number of Deferred Ambia Consideration Shares issuable by the Company on the six- and 12-month anniversaries of the Ambia Closing was determined based on the 20-day trailing volume-weighted average price of the Company’s common stock after market close on the business day immediately prior to the issuance date of the applicable shares (the “VWAP Value”); provided that the VWAP Value for the calculation of the actual number of Deferred Ambia Consideration Shares issuable by the Company will not be more than $2.8102 per share or less than $1.4988 per share. Additionally, the number of Deferred Ambia Consideration Shares issuable by the Company is subject to adjustment pursuant to customary working capital and balance sheet adjustment terms and subject to offset for certain indemnifiable damages in accordance with the Ambia MIPA.

(8) SAFE Agreement

Third SAFE

On May 13, 2024, the Company entered into a third SAFE (the “Third SAFE”) with the Rodgers Massey Freedom and Free Markets Charitable Trust (the “Purchaser”), in connection with the Purchaser investing $1.0 million in the Company. The Third SAFE is convertible into shares of the Company’s common stock upon the initial closing of a bona fide transaction or series of transactions with the principal purpose of raising capital, pursuant to which the Company issues and sells shares of its common stock in an Equity Financing, at a per share conversion price which is equal to 50% of the price per share of the Company’s common stock sold in the Equity Financing. If the Company consummates a change of control prior to the termination of the Third SAFE, the Purchaser will be automatically entitled to receive a portion of the proceeds of such liquidity event equal to $1.0 million, subject to certain adjustments as set forth in the Third SAFE. The Third SAFE is convertible into a maximum of 2,750,000 shares of the Company’s common stock, assuming a per share conversion price of $0.275, which is the product of (i) $0.55, the closing price of the Company’s common stock on May 13, 2024, multiplied by (ii) 50%. Given that the SAFE could be settled in cash or a variable number of shares, the Company has accounted for the instrument as a liability at its fair value.

The SAFE liability represents the estimated fair value of the Company’s obligation to issue equity in the future. The fair value of the Third SAFE approximated $0.6 million and $0.5 million as of March 29, 2026 and December 28, 2025, respectively. Refer to Note 5 – Fair Value Measurements for details.

On April 23, 2026, the SAFE was converted and exchanged into $1.0 million principal amount of the Company’s 10.0% convertible secured notes due 2029. Refer to Note 18 – Subsequent Events for details.

Standby Equity Purchase Agreement and $1.9 Million Note

On January 27, 2026 (the “Effective Date”), SunPower entered into a Standby Equity Purchase Agreement (the “SEPA”) with YA II PN, LTD., a Cayman Islands exempt limited company (“YA”). Pursuant to the SEPA, YA agreed to advance up to $20.0 million (the “Pre-Paid Advances”) to the Company in the form of convertible promissory notes (each “Promissory Note”), subject to the terms and conditions of the SEPA. Each Promissory Note bears interest at 0% per annum, which increases to 18% per annum upon the occurrence and continuance of an Event of Default (as defined in the Promissory Notes) for so long as such event remains uncured. Each tranche is funded at a 10% discount to its principal amount. The Promissory Notes are initially convertible into 540.5405 shares of the Company’s common stock per $1,000 principal amount, subject to adjustment.

The SEPA also provides the Company the right, subject to certain conditions, to require YA to purchase up to $25.0 million of the Company’s common stock (“Commitment Amount”) through January 27, 2029.

In connection with the SEPA, the Company paid YA total fees of $0.4 million consisting of $0.05 million of cash and 175,000 shares of the Company’s common stock, with a fair value of $0.3 million, as a due diligence, structuring and commitment fee.

The SEPA will automatically terminate on the earliest to occur of (i) January 27, 2029 or (ii) the date on which YA has purchased from the Company under the SEPA the Commitment Amount in full. The Company may terminate the SEPA at any time upon five trading days’ prior written notice to YA, provided that there are no outstanding advance notices under which the Company is yet to issue shares of its common stock, there are no amounts outstanding under the Promissory Notes, and provided that the Company has paid all amounts owed to YA pursuant to the SEPA. The Company and YA may also agree to terminate the SEPA by mutual written consent.

On January 27, 2026, the first Pre-Paid Advance was disbursed. The gross amount of the borrowing under the Pre-Paid Advance was $1.9 million which was advanced under a Promissory Note (“$1.9 Million Note”), and the Company received net proceeds of $1.71 million after the contractual discount. The $1.9 Million Note matures on January 27, 2027, which may be extended at YA’s option. The Company’s rights for further Pre-Paid Advances under the SEPA terminated pursuant to the terms of the SEPA.

The Company elected the fair value option under ASC 825, Financial Instruments, for the $1.9 Million Note. Accordingly, the $1.9 Million Note is recorded at fair value upon issuance and are subsequently remeasured at fair value at each reporting date, with changes in fair value recognized in “non-operating Other non-operating income, net” in the Company’s unaudited condensed consolidated statements of operations and comprehensive income. As a result of this election, the original issue discount, transaction costs, and embedded conversion features are not separately accounted for and are instead reflected in the fair value of $1.9 Million Note. The $1.9 Million Note is classified as a Level 3 liability within the fair value hierarchy established by ASC 820, Fair Value Measurement, due to the use of significant unobservable inputs in the valuation. Refer to Note 5 – Fair Value Measurements for a description of the inputs and assumptions used in the valuation of the $1.9 Million Note.

The initial amount of the $1.9 Million Note was recorded at its estimated fair value of $1.7 million on the issuance date. As of March 29, 2026, the $1.9 Million Note had a fair value of $1.5 million. The change in the fair value of the $1.9 Million Note was included in “Other non-operating income, net” within the unaudited condensed consolidated statement of operations and comprehensive income in the thirteen week period ended March 29, 2026.

March 2026 Bridge Note

On March 6, 2026, the Company entered into a purchase agreement (“Purchase Agreement”) with YA pursuant to which the Company issued a convertible debenture in the principal amount of $10.0 million (the “March 2026 Bridge Note” and collectively with the $1.9 Million Note, the “Yorkville Notes”). The Company received net proceeds of $9.0 million at issuance, after deducting fees payable under the Purchase Agreement. The March 2026 Bridge Note matures on March 6, 2027, unless extended at YA’s option. The March 2026 Bridge Note bears interest at 0% per annum; however, upon the occurrence and continuance of an event of default, the interest rate increases to 18% per annum.

The Company elected the fair value option under ASC 825 for the March 2026 Bridge Note. As a result, the March 2026 Bridge Note is carried at fair value, with changes in fair value recognized in earnings within “non-operating Other non-operating income, net” in the Company’s unaudited condensed consolidated statements of operations and comprehensive income. As a result of this election, the original issue discount, transaction costs, and embedded conversion features are not separately accounted for and are instead reflected in the fair value of the March 2026 Bridge Note. The March 2026 Bridge Note is classified as a Level 3 liability within the fair value hierarchy established by ASC 820 due to the use of significant unobservable inputs in the valuation. See Note 5 – Fair Value Measurements for additional information regarding the valuation of the March 2026 Bridge Note, including key assumptions and valuation methodologies.

The initial amount of the March 2026 Bridge Note was recorded at its estimated fair value of $9.0 million on the issuance date. As of March 29, 2026, the March 2026 Bridge Note had a fair value of $9.5 million. The change in the fair value of the March 2026 Bridge Note was included in “Other non-operating income, net” within the Company’s unaudited condensed consolidated statement of operations and comprehensive income in the thirteen week period ended March 29, 2026.

The March 2026 Bridge Note required installment payments on May 6, 2026, June 6, 2026, July 6, 2026, August 6, 2026, and September 6, 2026 (each, an “Installment Date”). On each Installment Date, the Company was required to pay an amount equal to (i) $2.0 million of principal, (ii) a payment premium of $0.06 million, and (iii) any accrued and unpaid interest (collectively, the “Installment Amount”). The Company may satisfy each Installment Amount, at its option, (a) in cash, (b) by submitting an advance notice pursuant to the SEPA, or (c) through a combination of cash and such advance notice. On April 21, 2026, the Company and YA agreed to amend the Installment Dates in connection with a $5.0 million prepayment of the March 2026 Bridge Note. As amended, on each of May 5, 2026, June 5, 2026, July 5, 2026 and August 5, 2026, the Company is required to pay an amount equal to (i) $1.25 million of principal, (ii) a payment premium of $0.0375 million, and (iii) any accrued and unpaid interest. Refer to Note 18 – Subsequent Events for details.

At any time after issuance, YA may convert all or a portion of the outstanding principal balance into shares of the Company’s common stock at an adjusted fixed conversion price of $1.64 per share (the “Fixed Price”). In addition, any Installment Amount that remains unpaid following an Installment Date may be converted at a price equal to 95% of the volume weighted average price (“VWAP”) of the Company’s common stock during the five trading days immediately preceding the conversion date, subject to a minimum conversion price equal to the then-applicable floor price.

The Company may, at its option, redeem all or a portion of the outstanding balance of the March 2026 Bridge Note (an “Optional Redemption”) upon written notice to YA, provided that the VWAP of the Company’s common stock at the time of such notice is less than the Fixed Price. The redemption price equals (i) the principal amount redeemed, (ii) a premium of 3% of such principal amount, and (iii) any accrued and unpaid interest; provided that the premium does not apply to Optional Redemptions completed on or prior to April 30, 2026.

Seller Note – related party

On September 24, 2025, the Company issued a note payable to CPP (“Seller Note”) in connection with the Company’s acquisition of 100% of the membership interests in Sunder and concluded that the Seller Note is a related party obligation (see Note 3 – Business Combinations). The Seller Note has an original principal amount of $20.0 million. The Seller Note bears interest at 7.0% per annum, compounded at the end of each calendar quarter. Interest is due and payable concurrent with the payment of the principal balance. The maturity date of the Seller Note was initially the earlier of (i) May 15, 2026 and (ii) the date on which all amounts under the Seller Note otherwise become due and payable following an event of default. The Seller Note must also be repaid in the event of a change of control of the Company or the sale of all or substantially all of the consolidated assets of the Company and its subsidiaries. The Seller Note includes customary events of default, including: (a) the Company’s failure to pay the Seller Note when due, (b) the Company’s voluntary or involuntary bankruptcy, (c) the Company’s liquidation or dissolution, (d) a change of control of the Company, (e) the Company’s material breach of the covenants applicable to the Company under the Seller Note, subject to applicable cure periods, and (f) if any of the Company’s representations or warranties made in the Seller Note were untrue in any material respect when made. Management concluded that the carrying value of the Seller Note approximates its fair value due to the short-term nature of the obligation.

On March 5, 2026, the Company entered into an amendment of the Seller Note (“Amendment”) providing that if the terms of the SEPA would restrict repayment of the Seller Note on May 15, 2026, then the maturity date of the Seller Note will be extended to the earlier of (a) the date that is two business days following the date on which the Seller Note may be repaid pursuant to the restrictions set forth in the SEPA Debenture and (b) September 30, 2026 (or, if the registration statement required to be filed pursuant to the Registration Rights Agreement has not been declared effective prior to April 30, 2026, then the outside maturity date will extend to December 31, 2026). Additionally, the Company and CPP agreed that the interest rate applicable to the Seller Note will increase to 10.0% per annum if the principal amount of the Seller Note remains outstanding after May 15, 2026. As an inducement to CPP’s agreement to the foregoing, the Amendment also provides that, within two business days following approval by the Company’s stockholders of the issuance of shares under the Sunder MIPA in accordance with applicable Nasdaq rules, the Company will issue the remaining shares of common stock otherwise issuable to CPP pursuant to the Sunder MIPA. On April 8, 2026, the Company issued the remaining 6.7 million shares of the Company’s common stock due under the Seller Note.

On April 23, 2026, the Company and CPP entered into the A&R Seller Note with a revised principal amount of $7.0 million. Refer to Note 18 – Subsequent Events for details.

Holders of the 7.0% Senior Notes may convert all or any portion of their 7% Notes at any time, in integral multiples of $1,000 principal amount, at the option of the holder. Upon conversion, the Company may satisfy its conversion obligation by paying or delivering, as the case may be, cash, shares of common stock or a combination of cash and shares of common stock, at the Company’s election, in the manner and subject to the terms, conditions and limitations provided in the Indenture. The 7.0% Senior Notes may be declared due and payable at the option of the holder upon an event of default and upon a qualifying change of control event. There are no financial covenants. As described below, the Company has issued multiple tranches under this Indenture.

The conversion rate for the 7.0% Notes was initially 467.8363 shares of common stock per $1,000 principal amount of 7.0% Notes. The conversion rate for the 7.0% Notes is subject to adjustment from time to time in accordance with the terms of the Indenture, and as of December 28, 2025 the 7.0% Notes were convertible at the rate of 584.7953 shares of common stock per $1,000 principal amount of the notes. In addition, upon a conversion of the 7.0% Notes, following certain corporate events that occur prior to the maturity date of the 7.0% Notes or if the Company delivers a notice of redemption in respect of the 7.0% Notes, the Company will, under certain circumstances, increase the conversion rate of the 7.0% Notes for a holder who elects to convert its 7.0% Notes following September 16, 2025, in connection with such a corporate event that occurs prior to the maturity date, or if the Company delivers a notice of redemption in respect of the 7.0% Notes.

September 2024 Notes

The Company issued an aggregate of $80.0 million of 7.0% Notes to various lenders (the “September 2024 Notes”), of which the Company received cash proceeds in two tranches of $66.8 million and $13.0 million in fiscal 2024. The remainder was received in fiscal 2025.

The cash proceeds of $66.8 million included $4.0 million from the Rodgers Family Freedom and Free Markets Charitable Trust (“Massey Charitable Trust”), a related party, and $4.0 million from the Rodgers Revocable Trust (collectively with Massey Charitable Trust, “Massey Trusts”), also a related party. In fiscal 2025, a holder of $0.75 million of the September 2024 Notes became a member of the Company’s board of directors and this note is now deemed to be with a related party beginning in fiscal 2025. As the $66.8 million of notes were issued with a debt discount in excess of the principal amount, the initial net carrying amount of the September 2024 Notes was zero. The debt discount is being amortized on a straight-line basis over the term of the September 2024 Notes.

In December 2024, the Company received proceeds of $13.0 million in a second tranche. The Company recognized a $10.9 million debt discount in connection with these additional proceeds. The effective interest rate on this tranche is 64% as of March 29, 2026.

Certain holders of the September 2024 Notes exercised their rights to convert this debt to shares of the Company’s common stock. In the thirteen week period ended March 29, 2025 $2.8 million of the September 2024 Notes were converted into 1.6 million shares of the Company’s common stock. In the fiscal year ended December 29, 2025, $14.7 million of the September 2024 Notes were converted into 8.6 million shares of the Company’s common stock.

The carrying amount of the convertible September 2024 Notes was as follows (in thousands):

	As of
	March 29,			December 28,
	2026			2025
September 2024 Notes	$	62,543		$	65,293
Less Unamortized debt discount		(43,797	)		(48,615	)
Net carrying amount of September 2024 Notes	$	18,746		$	16,678

In the thirteen week periods ended March 29, 2026 and March 30, 2025, total interest expense was $5.9 million and $5.0 million with coupon interest expense of $1.1 million and $1.4 million, respectively, and debt discount and issuance costs of $4.8 million and $3.6 million, respectively. Of the coupon interest expense, related party interest expense was $0.2 million and $0.1 million in the thirteen week periods ended March 29, 2026 and March 30, 2025, respectively. Related party amortization expense was $0.5 million and $0.5 million in the thirteen week periods ended March 29, 2026 and March 30, 2025, respectively.

September 2025 Notes

On September 21, 2025, the Company issued an additional $22.0 million of the 7.0% Notes (the “September 2025 Notes”) pursuant to the Indenture to various parties. The September 2025 Notes contain a conversion option which required bifurcation and recognition of a derivative, and the Company recorded a derivative liability of $15.4 million on the issuance date. The Company also recognized a $3.6 million debt discount and issuance costs in connection with the September 2025 Notes. The debt issuance costs include an estimate of the value of a warrant issued in the second quarter of fiscal 2026 to the entity that arranged the financing. The effective interest rate on the September 2025 Notes approximated 78% as of March 29, 2026. The net proceeds from the issuance of the September 2025 Notes were principally used to pay a portion of the cash consideration for the Company’s acquisition of Sunder.

The carrying amount of the September 2025 Notes, inclusive of the fair value of the derivative liabilities was as follows (in thousands):

	As of
	March 29,			December 28,

In the thirteen week period ended March 29, 2026, total interest expense was $0.6 million with coupon interest expense of $0.4 million and debt discount and issuance costs of $0.2 million.

On April 21, 2026, the Company entered into separately- and privately- negotiated exchange agreements (the “Exchange Agreements”) with certain holders of the 7.0% Notes to repurchase $21.25 million aggregate principal amount of outstanding 7.0% Notes in exchange for (i) an aggregate of 18.8 million shares of the Company’s common stock and (ii) approximately $0.5 of accrued interest payable under the exchanged 7.0% Notes.

Indemnification Agreements

From time to time, in its normal course of business, the Company may indemnify other parties with which it enters into contractual relationships, including customers, lessors, and parties to other transactions with the Company. The Company may agree to hold other parties harmless against specific losses, such as those that could arise from breach of representation, covenant or third-party infringement claims. It may not be possible to determine the maximum potential amount of liability under such indemnification agreements due to the unique facts and circumstances that are likely to be involved in each particular claim and indemnification provision. Historically, there have been no such indemnification claims. In the opinion of management, any liabilities resulting from these agreements would not have a material adverse effect on the business, financial position, results of operations, or cash flows of the Company.

Settlement of dispute with SunPower Debtors Bankruptcy Estate

Following the consummation of the acquisition of certain assets and assumption of certain liabilities of SunPower Debtors on September 30, 2024, certain matters pertaining to the acquisition were under dispute which included 1) amounts owed to and from the buyer and seller with respect to amounts held in escrow related to the consideration transferred, 2) the right to the cash acquired in the acquisition, and 3) the right for the Company to sell and collect for certain solar systems that were acquired as a part of the acquisition that were sold or are to be sold to homebuilders within the New Homes Business. On June 25, 2025, all matters under dispute were resolved by the Company and the SunPower Bankruptcy Estate. Matters 1) and 2) were resolved with such that no amounts were required to be paid (or received) by the Company. Matter 3) was resolved such that the Company has the right to sell the related inventory acquired and collect the underlying sales price for the sale of the solar system. In connection with each system sold, the Company is required to remit a portion of the sales price to the SunPower Bankruptcy Estate. The impact of the related settlement is not anticipated to be material.

Legal Matters

The Company is a party to various legal proceedings and claims which arise in the ordinary course of business. The Company records a liability when it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. If the Company determines that a loss is reasonably possible and the loss or range of loss can be reasonably estimated, the Company discloses the reasonably possible loss. The Company adjusts its accruals to reflect the impact of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular case. Legal costs are expensed as incurred. Although claims are inherently unpredictable, the Company is not aware of any matters that may have a material adverse effect on the Company’s business, financial position, results of operations, or cash flows. The Company has a loss contingency for legal settlements of $9.5 million recorded within accrued expenses and other current liabilities on its consolidated balance sheets as of March 29, 2026, and December 28, 2025, respectively.

SolarPark Litigation

In January 2023, SolarPark Korea Co., LTD (“SolarPark”) demanded approximately $80.0 million during discussions between the Company and SolarPark. In February 2023, the Company submitted its statement of claim seeking approximately $26.4 million in damages against SolarPark. The ultimate outcome of this arbitration is currently unknown and could result in a material liability to the Company. However, the Company believes that the allegations lack merit and intends to vigorously defend all claims asserted.

On March 16, 2023, SolarPark filed a complaint against the Company in the U.S. District Court for the Northern District of California (“the Court”). The complaint alleges a civil conspiracy involving misappropriation of trade secrets, defamation, tortious interference with contractual relations, inducement to breach of contract, and violation of California’s Unfair Competition Law. The complaint indicates that SolarPark has suffered in excess of $220.0 million in damages.

On May 11, 2023, SolarPark filed a motion for preliminary injunction to seek an order restraining the Company from using or disclosing SolarPark’s trade secrets, making or selling shingled modules other than those produced by SolarPark, and from soliciting solar module manufacturers to produce shingled modules using Solaria’s shingled patents. On May 18, 2023, the Company responded by filing a motion for partial dismissal and stay. On June 1, 2023, SolarPark filed an opposition to the Company’s motion for dismissal and stay and a reply in support of their motion for preliminary injunction. On June 8, 2023, the Company replied in support of its motion for partial dismissal and stay. On July 11, 2023, the Court conducted a hearing to consider SolarPark’s and the Company’s respective motions. On August 3, 2023, the Court issued a ruling, which granted the preliminary injunction motion with respect to any purported misappropriation of SolarPark’s trade secrets. The Court’s ruling does not prohibit the Company from producing shingled modules or from utilizing its own patents for the manufacture of shingled modules. The Court denied SolarPark’s motion seeking a defamation injunction. The Court denied the Company’s motion to dismiss and granted the Company’s motion to stay the entire litigation pending the arbitration in Singapore. On September 1, 2023, the Company filed a Limited Notice of Appeal to appeal the August 2023 order granting SolarPark’s motion for preliminary injunction. On September 26, 2023, the Company filed a Notice of Withdrawal of Appeal and will not appeal the Court’s Preliminary Injunction Order. Between August 2023 and March 2024, the parties were engaged in discovery negotiations and the Company produced documents to SolarPark. The Company produced its last set of documents on March 14, 2024. On August 14, 2025, the Court held a virtual hearing and revived the case. SolarPark subsequently amended the complaint, and the Company responded on October 14, 2025, with a motion to dismiss the complaint in its entirety. The Company also believes it has valid counterclaims to pursue against SolarPark.

The Court heard argument regarding the Company’s partial motion to dismiss on February 12, 2026. On April 8, 2026, the Court granted-in-part and denied-in-part the Company’s partial motion to dismiss. The Court denied the Company’s motion as to the breach of contract claim and granted the motion as to fraudulent inducement, tortious interference, and injunctive relief. The Court dismissed the tortious interference and injunctive relief claims with prejudice but granted SolarPark’s leave to amend its fraudulent inducement claim. On April 28, 2026, SolarPark filed a notice stating that it did not intend to amend its complaint to refile a fraudulent inducement claim. SolarPark now intends to proceed only on the surviving claims (misappropriation of trade secrets and breach of contract). On April 29, 2026, the Court set a case management conference for June 4, 2026, and a deadline for filing a joint case management statement by May 28, 2026. The Company intends to answer the complaint and file counterclaims.

No liability has been recorded on the Company’s consolidated financial statements as the likelihood of a loss is not probable at this time.

Siemens Litigation

On July 22, 2021, Siemens Government Technologies, Inc. (“Siemens Government Technologies”) filed a lawsuit against Solaria Corporation in Fairfax Circuit Court (the “Circuit Court”) in Fairfax, Virginia. On July 27, 2023, Siemens Government Technologies moved to amend the complaint to add Siemens Industry Inc. as a co-plaintiff. This motion was granted on August 25, 2023. On October 23, 2023, Siemens Government Technologies and Siemens Industry Inc. (collectively, “Siemens”) and Solaria Corporation stipulated to add Solar CA, LLC as a co-defendant. Solaria Corporation and Solar CA, LLC (collectively, the “Subsidiaries”) are both wholly-owned subsidiaries of the Company. In the lawsuit, Siemens alleged that the Subsidiaries breached express and implied warranties under a purchase order that Siemens placed with the Subsidiaries for a solar module system. Siemens claimed damages of approximately $6.9 million, inclusive of amounts of the Subsidiaries’ indemnity obligations to Siemens, plus attorneys’ fees.

On February 22, 2024, the Circuit Court issued an order against the Subsidiaries which awarded Siemens approximately $6.9 million, inclusive of the amounts of the Subsidiaries’ indemnity obligations to Siemens, plus attorneys’ fees, the amount of which would be determined at a later hearing. On March 15, 2024, Siemens filed a motion seeking to recover $2.67 million for attorneys’ fees, expenses, and pre-and post-judgment interest. The Company opposed Siemens’ motion for attorneys’ fees, expenses, and pre- and post-judgment interest on April 5, 2024. On June 17, 2024, the Circuit Court entered a final order which awarded Siemens a total of $2.0 million in attorneys’ fees and costs. The Company appealed these judgments.

In addition to the above, on August 19, 2024, Siemens applied for the enforcement to a sister state judgment in the Superior Court of Alameda, California and the court entered a judgement in favor of Siemens. On December 9, 2024, Siemens moved to amend the judgment to add the Company as a judgement debtor. The Subsidiaries opposed the Siemens motion. On June 30, 2025, the California court found that the Company should be added as a judgment debtor party in California. In addition, the parties argued the appeal of the underlying Virginia litigation on July 24, 2025. On September 23, 2025, the Virginia Court of Appeals issued a decision on the appeal, affirming the original lower court decision and judgment against the Company. The Alameda County litigation has continued with several upcoming deadlines related to the already-noticed appeal and Siemens’ motion for fees and costs.

The Company recognized $6.9 million as a legal settlement loss related to this litigation as of December 31, 2023. The Company recorded additional expense of $1.1 million and $2.0 million within discontinued operations in the years ended December 28, 2025 and December 29, 2024, respectively, for attorneys’ fees, expenses, and pre-judgment interest related to this matter. The legal settlement liability associated with this matter is included within accrued expenses and other current liabilities on the Company’s consolidated balance sheet as of December 28, 2025.

On December 4, 2025, the Company entered into a global Settlement Agreement (“Settlement Agreement”) with Siemens to resolve the case and other related cases as well as to resolve potential claims related to Siemens’ Atwater Wastewater Treatment Plant. In exchange for full releases, the Company agreed to pay Siemens $9.5 million spread across four payments to be made at the end of each calendar quarter during 2026. If the Company successfully engages in any form of new financing or new debt worth $1.0 million or more, or successfully obtains shareholder approval for the issuance of additional shares in connection with the raise of additional funds and/or any merger or acquisition activity, the next due quarterly payment to Siemens (if any) becomes immediately due and payable (collectively, the “Fundraise Provision”). The settlement payment to Siemens is secured by a first-priority continuing security interest in $9.5 million of Company collateral. This security interest is reduced on a one-to-one basis as the settlement payments are made.

LGCY Power, LLC Matter

LGCY Power, LLC (“LGCY”) markets and sells residential solar energy systems throughout the United States, and is a competitor of the Company. In 2019, LGCY filed suit against Sunder and several individuals associated with Sunder. LGCY asserts claims of over $16.0 million against Sunder and its associated individuals. LGCY’s claims against Sunder and its associated individuals center on the alleged misappropriation of LGCY’s confidential information, the alleged wrongful solicitation of LGCY’s customers and potential customers, and the alleged wrongful solicitation of LGCY’s sales representatives. In addition, several of the Sunder associated individuals have filed counterclaims against LGCY for declaratory relief, unjust enrichment, and breach of contract based on LGCY’s failure to pay these individuals earned sales commissions following their resignations as LGCY sales managers. LGCY denies these claims. The Company denies LGCY’s claims.

The Company has assumed the defense of the case, including the costs of defense, following the Company’s acquisition of Sunder in September 2025. Under the terms of the Sunder MIPA, the Seller agreed to indemnify the Company in the event of damages (such as a settlement or an adverse judgement) stemming from LGCY’s claims, separate and apart from their other indemnification obligations or limitations in the Sunder MIPA. Discovery is complete and no trial date has been set. Both sides have filed various summary judgment motions, and oral arguments for these motions are scheduled for July 2, 2026.

Based upon information currently available, management is unable to determine the probability of an adverse outcome or to reasonably estimate the amount or range of potential loss, if any. Accordingly, no provision for loss has been recorded in the accompanying consolidated financial statements. While the ultimate resolution of these matters could have a material effect on the Company’s results of operations, cash flows, or financial position, management believes that the resolution will not have a material adverse effect on the Company’s financial condition

Letters of Credit

The Company had $1.1 million and $3.5 million of outstanding letters of credit as of March 29, 2026 and December 28, 2025, respectively. The Company is required to maintain specified amounts of cash as collateral in segregated accounts to support the letters of credit issued thereunder. As discussed in Note 2 – Summary of Significant Accounting Policies, the cash collateral in these restricted cash accounts was $1.1 million and $3.8 million at each of March 29, 2026 and December 28, 2025, respectively.

(12) Income Taxes

The Company’s income tax expense for interim periods is computed using an estimated annual effective tax rate applied to year-to-date ordinary income or loss, adjusted for the tax effects of discrete items recognized in the period in which they occur.

The Company recognized an income tax benefit of $0.6 million and nil in the thirteen week periods ended March 29, 2026, and March 30, 2025, respectively.

The Company’s effective tax rate was 10.4% and nil for the thirteen week periods ended March 29, 2026, and March 30, 2025, respectively. The effective tax rate for the thirteen week period ended March 29, 2026 differs from the U.S. statutory rate of 21.0% primarily because of permanent differences due to fair value adjustments and the valuation allowance against most of the deferred tax assets. The effective tax rate for the thirteen week period ended March 30, 2025 differs from the U.S. statutory rate of 21.0% primarily because of permanent differences due to fair value adjustments, share-based compensation related to stock options, non-deductible meals and entertainment, and state taxes.

As a result of the Company’s history of net operating losses, the Company has provided a full valuation allowance against its deferred tax assets. During the thirteen week period ended March 29, 2026, the Company recorded a $0.8 million decrease in its valuation allowance primarily related to recognition of deferred tax liabilities in connection with the Cobalt acquisition.

As of the thirteen week periods ended March 29, 2026 and March 30, 2025, the Company had no unrecognized tax benefits. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income tax expense.

(13) Common Stock and Common Stock Warrants

The Company has authorized the issuance of 1,000,000,000 shares of common stock and 10,000,000 shares of preferred stock as of March 29, 2026. No preferred stock has been issued and none are outstanding as of March 29, 2026.

Common stock purchase agreement

On July 16, 2024, the Company entered into a common stock purchase agreement with White Lion Capital, LLC (“White Lion”), as amended on July 24, 2024 (“White Lion SPA”), and a related registration rights agreement for an equity line of credit financing facility. Pursuant to the White Lion SPA, the Company has the right, but not the obligation, to require White Lion to purchase, from time to time, up to $30 million in aggregate gross purchase price of newly issued shares of the Company’s common stock, subject to the caps and certain limitations and conditions set forth in the White Lion SPA, including terms that restrict the ability of the Company to issue shares of common stock to White Lion that would result in White Lion beneficially owning more than 9.99% of the Company’s outstanding common stock.

On August 14, 2024, the Company entered into Amendment No. 2 to the White Lion SPA (collectively with the White Lion SPA “White Lion Amended SPA”). The White Lion Amended SPA provides that the Company may notify White Lion to exercise the Company’s right to sell shares of its common stock by delivering an Hour Rapid Purchase Notice. If the Company delivers an Hour Rapid Purchase Notice, the Company shall deliver to White Lion shares of common stock not to exceed the lesser of (i) five percent of the Average Daily Trading Volume on the date of an Hour Rapid Purchase Notice and (ii) 100,000 shares of common stock. The closing of the transactions under an Hour Rapid Purchase Notice will occur one Business Day following the date on which the Hour Rapid Purchase Notice is delivered. At such closing, White Lion will pay the Company the Hour Rapid Purchase Investment Amount equal to the number of shares of common stock subject to the applicable Hour Rapid Purchase Notice multiplied by the lowest traded price of the Company’s common stock during the one-hour period following White Lion’s consent to the acceptance of the applicable Hour Rapid Purchase Notice.

On January 11, 2026, the Company and White Lion entered into Amendment No. 3 (“Amendment No. 3”) to the White Lion SPA. Amendment No. 3 extends the commitment period under the White Lion SPA (the “Commitment Period”) to the earlier of December 31, 2027 and the date on which White Lion has purchased an aggregate number of shares of the Company’s common stock equal to the Commitment Amount (as defined below). Further, Amendment No. 3 increases, subject to approval by the Company’s stockholders, the commitment amount under the Purchase Agreement to $55.0 million of shares of its common stock (the “Commitment Amount”), which the Company may elect to sell to White Lion pursuant to the White Lion SPA, from time to time in the Company’s sole discretion, during the Commitment Period.

In addition, Amendment No. 3 adds an option for the Company to submit three hour rapid purchase notices to White Lion that, if accepted by White Lion and otherwise delivered in accordance with the Purchase Agreement, would enable the Company to sell shares of its common stock to White Lion based on the lowest traded price of the Company’s common stock during the three-hour valuation period following White Lion’s written acceptance of a three hour purchase notice.

In the thirteen week period ended March 29, 2026, the Company issued an aggregate of 4.6 million shares of the Company’s common stock for total proceeds of $7.0 million. As of March 29, 2026, the Company has issued an aggregate of 11.5 million shares of the Company’s common stock for total proceeds of $20.4 million.
